Periodic Golay pairs of length 72

Dragomir Z. Djokovic, Ilias S. Kotsireas

We construct supplementary difference sets (SDS) with parameters $(72; 36, 30; 30)$ . These SDSs give periodic Golay pairs of length 72. No periodic Golay pair of length 72 was known p…

Charm bracelets and their application to the construction of periodic Golay pairs

Dragomir Z Djokovic, Ilias Kotsireas, Daniel Recoskie +1

A $k$ -ary charm bracelet is an equivalence class of length $n$ strings with the action on the indices by the additive group of the ring of integers modulo $n$ extended by the group…
